MAN! This was a great movie! I absolutely LOVE a good horror movie, and they are so hard to come by, we never get to see any. BUT this one....was GREAT!
The idea is fantastic - some maniac picks 2 people that are linked to each other in their lives, but probably don't know it. Then there's some sort of "test" where one has to die in order for the other to live - in this case, the main story is a DR who is cheating on his wife AND was once a suspect in these odd murders (there are quite a few of them, and they show the other ones, very cool!) and the private investigator following him wake up locked in a disgusting bathroom - each chained to the other side of the room. The killer leaves a recorded message for each of them, telling them what they need to do to live and consequences if they don't - in the killer's mind, he wants to make these people appreciate life more. Apparently, for the DR to live (and his wife and daughter to live), he must find a way to kill the other guy, Adam, chained up across the room. They are each given a saw - which they can use to cut off their foot to either escape or accomplish their task.
It's a great flick w/twists that we didn't see coming at all. And the flashbacks to the other competitions were great - super eerie, but great.
I highly recommend it - and am trying to figure out a way to get to see Saw2 when it comes out next Friday night.
